SLED ATTACHMENT FOR CYCLES.

srnorricn'rron forming part of Letters Patent No. 650,171, dated May 22,1900.

Application filed March 15, 1899- Serial No. 709,229. (NomodeL) .To aZZwhom it may concern:

Be it known that LOARL DANNEHL, of N euhauser, East Prussia, in theGerman Empire, have invented some new and useful Improvements in Meansfor Transforming Ordinary Cycles into a Sledge for Use on Snow or Ice;and I declare that the following is a full and clear description.

This invention has for its object new or improved fittings by means ofwhich it is possible to transform an ordinary cycle into a sledge foruse on snow or ice.

In the annexed drawings, Figure l represents in side view a cycle fittedwith the new arrangement. Fig. 2 is a back view. Figs. 3 to 12 representparticularconstructions in detail of the parts.

Ct is the runner or shoe of the sledge for the front wheel, secured tothe wheel in proper manner-for example, by clamps-and provided on itsfront part with a projection-piece for the protection of the tire.

b is a sledge-frame, on which is supported the cycle by means of thestruts c. The tie bars (1 of the cycle-frame will bear upon and havesupport on projections of bars 0, (fitted with felt, leather, or thelike,) whereupon there is obviated side motion of the cycle on thesledge. The back wheel, which serves as a driving-wheel, is providedwith the spiked sheath or cover 6, as follows: Figs. 6, 7, 10, and 12show details of the parts, which can be connected together in asuitable'manner. It is advantageous to consider the usual sizes of thepneumatic-tired cycles, so that the spiked or sheath cover can beappliedas well on cycles with wheels of twenty-six inches as on those oftwenty-eight inches in diameter. The spiked sheath in cross-section,Fig. 10, corresponds to the profile of the cycle-tire, and to secure thesame the air must first be allowed to escape from the pneumatic tire.Then separate sections or parts of the spiked sheath can be put on andconnected together. An example of such attachment means, with tonguepieces or flaps and slits or openings combined with headed screws, isrepresented in Figs. 11 and 12 in approximately-full size. After havingthus closed the spiked sheath the pneumatic tire is to be again filledwith air, which applies itself therefor to the inner groove or contourof the spiked sheath, so that there is provided a reliable connectionbetween the driving-wheel and its sheath without using special fasteningmeansbetween the two parts. The spikes 2f on the sheath e are purposelybent forward in direction of the course of the cycle to at once preventfracture of the same and to facilitate the grip on and withdrawal fromthe ice.

According to the nature of the ice or the snow cover care must be takento provide always a proper catch of the spikes of the backdriving-wheel, and therefore an arrangement is necessary for a preciseadjustment of the back wheel from its work. Penetration of the spikes isless required when the ice cover is even than when it is rough or whengoing over snow surfaces. This raising or placing of the back wheel inthe proper position of elevation can be secured by means of firstturning the lever h by means of the handcrank i and set-screw 7a. Thislever h is centered on the plug g, and said lever 71 has theextension-arms Z, attached to the framingabars 0. Thus by raising orlowering the lever 72. can be efiected a higher or lower placement ofthe cycle-framing and therefore of the back wheel.

The front end of the sledge proper, b, is provided with acleanser-scraper m. This consists of vertically-disposed steelspring-strips working against each other sidewise. This cleanser mclears the way for the back-wheel sledge without finding resistance onthe hummocks of the ice and without gathering snow in front of thesledge.

A quadrangular form (see Fig. 3) can be given to the sledge or therunners of the sledge can be made shorter and an octagonal form can begiven to the framing, which last form is shown in Fig. 5 in side viewand in Fig. 4 in plan. In employing this form it is desirable to give tothe front and back frame an upward trend, so as to leave the-siderunnersfree. The quadrangular form of the sledge is in many cases preferable,as affording to the runners greater length and consequent advantage inriding over rough surfaces of the ice. The sledge can also be arrangedas a carrier to take other persons or goods. For this purpose there canbe applied on the sledge hined withlthe .sledgeb, consisting of twoua-bed for use. 3

diminished by setting the raising or lowering a footboard or platformand a seat, as now used with racing-sledges, or an extension of the,sledge can be :used for the carriageof goods.

According todifl'ering sizes of the cycle an adjustabili-ty of thesupporting-barso is desirable. For this purpose said bars a can beextended or shortened by thesliding tele-q seopic parts'o-and 'w,'whichcan be fixed by i means of the wing-nut n after the adjustment. In suchsupporting-bars c canlbe iii-i serted springs'zfor purpose of relievingshock when going upon rough ground.

It iscontemplated to arrangeonthis '1 pole To a regulating tight-nut or thelike, by means of whiehtheflpole can be lengthenedor shorten-ed,according to the size of the cycle.
